Compositions and methods for the treatment of macular degeneration
The present invention is directed to topical ophthalmic compositions of a lipophilic compound and an oligomeric or polymeric carrier wherein the compositions are useful in the treatment and prevention of macular degeneration. The invention also includes methods of treating macular degeneration by using a topical ophthalmic composition of a lipophilic compound and an oligomeric or polymeric carrier.
1. An ophthalmic composition comprising a compound of the following formula:
or a pharmaceutically acceptable salt thereof;
β-cyclodextrin sulfobutylether or a pharmaceutically acceptable salt thereof; and
an ophthalmically acceptable excipient;
wherein the compound is present at a concentration of about 0.05% w/v and wherein the ophthalmic composition comprises an aqueous solution.
2. The composition of claim 1 , wherein the β-cyclodextrin sulfobutylether is the sodium salt of β-cyclodextrin sulfobutylether.
3. The composition of claim 1 , wherein the aqueous solution is at a pH of 6.5-7.5.
4. The composition of claim 1 , wherein the β-cyclodextrin sulfobutylether or pharmaceutically acceptable salt thereof is at a concentration of about 9.5-20% w/v.
5. The composition of claim 1 , wherein β-cyclodextrin sulfobutylether or pharmaceutically acceptable salt thereof is at a concentration of about 9.5% w/v.
6. The composition of claim 1 , wherein the β-cyclodextrin sulfobutylether or pharmaceutically acceptable salt thereof is at a concentration of about 0.01-30% w/v.
7. The composition of claim 1 , wherein the β-cyclodextrin sulfobutylether or pharmaceutically acceptable salt thereof is at about 5-25% w/v.
8. The composition of claim 1 , wherein the β-cyclodextrin sulfobutylether or pharmaceutically acceptable salt thereof is at about 2% w/v.
9. The composition of claim 1 , wherein the ophthalmically acceptable excipient comprises a buffer.
10. The composition of claim 9 , wherein the buffer comprises a phosphate buffer.
